The Ministry of Public Health has issued regulations that applicants who have travelled from or through the countries which have been declared Yellow Fever Infected Areas must provide an International Health Certificate proving that they have received a Yellow Fever vaccination.

The International Health Certificate must be submitted together with the visa application form. The traveller will also have to present the said certificate to the Immigration Officer upon arrival at the port of entry in the Kingdom.
